s Claims.-

This invention relates in general to side plate constructions and in particular to such side -plate constructions adapted for sub-assembly work in the construction of freight cars.

For a number of years freight cars were built with a single side plate and were assembled piece by piece. Later it was discovered that by subassembly work cars could be built much faster and with greater ease. The tendency, however, was to still utilize a Single side plate or a single side plate made up of several parts which'had to be fastened together and then attached either to the side or to the roof. This type of construction, while permitting sub-assembly work, required expensive lifting beams and handling members for either the roof or the sides since one of these would be too exible to be handled b y itself. It is an object, therefore, of the present invention to provide a two-part side plate so arranged that one part can be attached to thereof and the otherA to the side in sub-assemblies.

A further object of the invention is the provi- Y sion of a side plate made up of at least two parts andy arranged to accommodate therebetween the Side Wall sheets and carlines.

A still'further object of the invention is the provision of a side plate so arranged that the carline ends may -be interposed `between parts of the side plate and tie the side plate parts together.

lAryet further object of the invention is the provision of a side plate construction having the parts -so arranged as to permit carlines of considerable depth to be attached thereto.

These and other objects of the invention will be apparent to persons skilled in the art from a studyof the following description and accompanyingdrawing, in which: n

Fig. 1 is a sectional View through the roof and side wall of a freight car; o

Fig. 2 is a sectional view-taken through the roof andsubstantially on line 2,-2 of Fig. 1; Fig. 3 is an elevational view of theimproved construction, and e Fig. 4 is a sectional view taken substantially on line 4-4 of Fig. 1. i

Referring now to the drawing in detail, it will be seen that the'upper Ypart of..V the side wall Wand the outer edge of the roof R are illustrated. It is, of course, understood that the car is symmetrical, that is, with the roof wall extending from side Wall ton sidewall to: complete the closure of the car body. As clearly shown, the side wall of the car includes side posts 2 of Z formation, to the outer flange of which are attached side sheets 4, while the inner flanges carry lining 6. The side wallcarried or inner .member of the side plate is of W cross section, having a depending flange 8 interposed between the posts and side sheets and being Welded tothe side posts. The upper edge of range amergves into a horizontal web portion Ill which Welded to the posts and this in turn merges into a vertical We-b portion l2 terminating in an inwardly .directed upper flange I4. This flange f I4 maybe either horizontal, that is, parallel to web` portion vlll or? as shown, it is inclined slightly so as to be in aplane. parallel to the under surface of the carlines. This W shaped inner plate member or side wall carried member will be attached to the side wall vsub-.assembly and stifen the same so thatY theeside wall may be readily transported from its sub-assembly point to the nal assembly point where the car will be .completed.

The roof is preferably made up of a plurality of nat sheets Z0 and .pressed sheets 22 which may be termed as carline Vforming roof sheets. These carline forming roof sheets are of general anged channel crossesection .having the web forming part of the roofA and the flanges 24 directed downwardly at the proper carline spacing and terminating in outwardly directed reanged portions 26, -These carline forming roofsheets will be alternated with the flat sheets v2i!P which latter overlap andere :spot welded or otherwise attached as. at 23/f-tothe flat web portions of the parlino.. forming-roof sheets. The vertically dlreotedhanses ofthe carline forming roof sheets areV spot weldedtor otherwiseattached as at 21 to the @vertical ,ahge 28 of .angIe vshaped .carline members, Yhavlnga horizontal flange 30 located substantially parallel to the reflange 26. The angularly shaped carlines are more or less of constant depth, but for. the end portions of vertical flanges 28 .cut at an angle corresponding to the slopeojfthe. roof but still leaving considerable depth ofL vertcalnangeat their ends. The sideedges of Athe .roof .have `attached thereto as by spot Welding. 32 a curved outer plate forming member. This plate forming member has the central portion 3.4Y .curved on an arc substantially concentric With .the point of. juncture of webs IIJ and l2 of tlienner plate member and this curved portion terminates in tangential portions 36 and 38, the tangential portionv 36 being attached to the edge of the roof sheets by welding, as previously referred t0,- and the Atangential portion 38 being attached to the side Walls by means of rivets 40. The ends of the carlines are overlapped by the tangential portion 36 to which they are attached by welding as at 42. In order that the roof sheets their flanges, by the carlines and by the curved plate forming member. Such a structure is sufficiently stiff to permit transportation from the sub-assembly point to which point it can be lowered onto the side walls and riveted thereto. Afterthe roof has been lowered into position and attached to, theside walls by means of the rivets 451, the horizontal flanges Si) of the carlines are attached to the inner edges the nal assembly point'atv of the flanges la of the W shaped inner plate forming member. carline resting upon flanges i4 will hold the roof while rivets d@ are being driven and that after-the flanges is are welded to the carline flanges 30, the carlines brace and connect the inner edges of the plate forming members to form in effect an `open sided box member with the open sides braced to utilize small platesor other means sealing the space between flange I4 and tangential portion 36. 'l-iowever, this sealing may be effected by extending the lining t upwardly to contact the tangential portion 36. I

While the construction has been shown more or less in detail with specic reference to the drawing, it will be obvious to persons skilled inthe art that various-modications and rearrangements of parts may be made without departing from the scope of the-invention as defined by the following claims.
